In the title compound, [Ca(C2H6OS)6][W6O19], the cation and anion both have a crystallographically imposed centre of symmetry. The CaII atom in the cation is coordinated by six O atoms from six dimethyl sulfoxide ligands in a distorted octa­hedral geometry. The [W6O19]2− isopolyanion possesses the well-known Lindqvist structure in which each WVI atom is coordinated by four μ2-O, one terminal O and one μ6-O atom.
